To change the layer visibility for a given view scale, modify the layer resource<br />
and save it back to the repository. See Modifying Maps and Layers (page 55)<br />
for details.<br />
The following example turns on the visibility for the Roads layer.<br />
$layers = $map->GetLayers();<br />
$roadsLayer = $layers->GetItem('Roads');<br />
$roadsLayer->SetVisible(True);<br />
NOTE Changing the visibility will have no effect until the map is saved and<br />
refreshed.<br />
